According to the accessible shape of described pad, can be only with a body part that pad-local coil component inspection patient is different.For example, except patient's upper body, patient for the second time by the time also can check his lower limb, as following among Fig. 6 and Fig. 7 for example the expression.
Description of drawings
Describe the present invention in detail by accompanying drawing below.Wherein:
Fig. 1 represents according to the basic project organization of the pad in the device of the present invention as example; And
Fig. 2 to Fig. 7 represents according to the accessible alteration of form of the pad in the device of the present invention.
The specific embodiment
Fig. 1 represents the basic project organization as example according to the pad K in the device of the present invention.
Pad K has the base plate BP that for example is designed to the elastoplast plate.On base plate BP, for example settle the air-locked rigid foam HS of one deck by bonding.
Air-locked rigid foam HS AS that leaves a blank wherein can settle the soft foam WS of gas-pervious strip.For example by air-locked rigid foam HS cutting or stamp out rectangular, to constitute the described AS of leaving a blank.
Leave a blank and inlay or the gas-pervious soft foam WS of filling among the AS.
Constitute a plate by the structure of forming by base plate BP, soft foam WS and rigid foam HS, this plate is inserted in air-locked sheath HUE that for example makes with polyvinylchloride.After inserting plate, this sheath HUE vacuum-tight is bondd.
The flexible pipe that sheath HUE has valve or is connected with sheath HUE is as the device EG that changes gas pressure, so that can deflate from sheath HUE.
Sheath HUE and plate and valve or flexible pipe finally constitute jointly according to pad K of the present invention, and here, pad K is designed to the support of at least one (not being shown specifically among the figure) local coil.
Fig. 2 represents to fill up the normal condition of K.For example, when in the inside of pad when having the environmental air pressure of standard, pad K is straight with tabular.If deflate from pad K by flexible pipe S now, pad K begins progressively to be bent upwards, and sees Fig. 3 and Fig. 4.
Because gas-pervious soft foam WS shrinks when deflating equably among Fig. 1, be bonded in the upward air-locked rigid foam HS of base plate BP during this period and keep dimensionally stable also thereby not to shorten, so described bending takes place.
Gas-pervious soft foam WS shrinks at the opposite side of base plate BP, and forces the distance that reduces between the rigid foam HS bar in this case.Producing one thus impels base plate BP bending and thereby causes whole pad K to be out of shape.
Described change of shape is relevant with the vacuum magnitude of formation in the pad K.
